One end of the pulley shaft 51 passes through the hull wire clamp bracket 10 and extends into the split rod 11. The conveying pulley 50 has limit plates on both sides, so that it is convenient to arrange the wire on the surface of the conveying pulley 50. Furthermore, the outer wall of the conveying pulley 50 is provided with anti-slip textures, which is convenient to increase the friction between the wire and the conveying pulley 50, ensuring that the conveying pulley 50 can effectively convey the wire; The one-way adjustment mechanism 60 is installed in the split rod 11 and is in transmission cooperation with the pulley shaft 51 in the swing cavity 12 .

[0019] As a preferred embodiment, on the basis of the above method, further, the suspension assembly 20 includes two connecting members 21, and the two connecting members 21 are connected and fixed by two groups of bolt assemblies 22, wherein one group of bolt assemblies 22 passes through the connecting member 21 and the hull wire clamp bracket 10, and the top and bottom of the connecting member 21 are both provided with through holes for the bolt assemblies 22 to pass through, and the two groups of bolt assemblies 22 both include screws and nuts, and the length of the screw at the bottom is greater than the length of the top screw, and the side wall of the hull wire clamp bracket 10 is provided with a U-shaped groove, and the U-shaped fixing frame 30 can be embedded and installed in the U-shaped groove, and the inner bottom wall of the hull wire clamp bracket 10 is also installed with a rubber gasket 13, and the U-shaped fixing frame 30 is embedded in the hull wire clamp bracket 10 to facilitate fitting the wire and not easily deviate, and the side wall of the hull wire clamp bracket 10 is also provided with a limit plate for limiting the sliding of the U-shaped fixing frame 30.

[0021] The fixing assembly 40 includes a socket 41, and a contact sleeve 42 is slidably mounted on the outer wall of the socket 41. There is a gap between the socket 41 and the contact sleeve 42, and a spring 43 is inserted into the gap. The two ends of the spring 43 respectively contact the socket 41 and the contact sleeve 42 to provide elastic potential energy for the contact sleeve 42 to slide upward.

[0023] As a preferred embodiment, on the basis of the above-mentioned manner, further, the one-way adjustment mechanism 60 includes a rotating handle 61 rotatably connected to the side wall of the split rod 11, and one end of the rotating handle 61 penetrates into the split rod 11 and is fixedly connected to an adjustment button 62, and the adjustment button 62 is elastically matched with the split rod 11 through an elastic member 63; The one-way adjustment mechanism 60 also includes a gear 64 fixedly connected to the pulley shaft 51. The adjustment button 62 has two limit ends 65, one of which is engaged with the gear 64. The rotating handle 61 has a triangular rotating portion and a cylindrical shaft portion. Rotating the rotating handle 61 can drive the adjustment button 62 to rotate. The elastic component 63 provides upward elastic potential energy for the adjustment button 62, so that the adjustment button 62 and the gear 64 are in contact with each other to achieve the purpose of one-way movement.

[0024] As a preferred embodiment, on the basis of the above-mentioned method, further, the elastic component 63 includes a spring 2 631 fixedly connected to the inner wall of the split rod 11, one end of the spring 2 631 is abutted against a card ball 632, and the side wall of the adjusting card button 62 is provided with a makeshift groove 633 for the card ball 632 to move. The inner wall of the split rod 11 has two limit columns for limiting the movement of the adjusting card button 62. When the limit end 65 moves to the limit column, the rotation of the adjusting card button 62 is limited. The side wall of the adjusting card button 62 is also provided with a fan-shaped groove, which facilitates the swinging of the adjusting card button 62, and the final point of the swing is when it abuts against the limit column.

[0025] Specifically, when the double-split transmission line suspension wire clamp is working / in use: install the wire in the hull wire clamp bracket 10, and then buckle the U-shaped fixing frame 30 on the hull wire clamp bracket 10 to limit the wire from being detached. When the wire needs to be pulled, the adjusting button 62 can be pried open. When the right limit end 65 of the adjusting button 62 is upward, the elastic member 63 is located in the left yield groove 633, and the conveying pulley 50 and the gear 64 can only rotate counterclockwise. When rotating, the gear 64 will push the adjusting button 62 to move clockwise. After moving to disengage from the gear 64, it will automatically reset to the gap between the two racks of the gear 64 under the push of the spring 2 631 to form a restricted state. In addition, the advantage of using the card ball 632 is that it will not cause large-scale wear when the adjusting button 62 rotates. When the left limit end of the adjusting button 62 is upward, the conveying pulley 50 can only rotate clockwise in the same way, thereby achieving The present invention provides one-way transportation, and during transportation, it is delivered through the conveying pulley 50, which can effectively reduce the wear between the wire and the hull wire clamp bracket 10. When it needs to be fixed, the contact sleeve 42 is pulled downward to insert the plug 31 at the bottom of the U-shaped fixing frame 30 into the socket 41. After insertion, the spring 43 pushes the contact sleeve 42 to contact the ball 45, so that the ball 45 restricts the plug 31, thereby completing the fixation of the wire. After fixation, a sealing and dustproof effect can also be formed between the socket 41, the plug 31 and the contact sleeve 42, effectively reducing the risk of rust on parts. When it needs to be disassembled, the contact sleeve 42 is also pressed downward. When the contact sleeve 42 slides downward, the ball 45 can be discharged from the arc groove 32. After losing the extrusion force of the contact protrusion 49, the plug 31 can be directly pulled outward, thereby completing the disassembly. This can also reduce the time for high-altitude workers to assemble, thereby being safer.
